DISINFECTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 644,158, dated February27, 1900.

Application filed September 5, 1899. Serial No. 729,430. (No model.)

To all whom it may concern:

Be it known that I, OARLOSTINE E. BLAKE, of the city of Minneapolis,county of I-Iennepin, State of Minnesota, have invented certain new anduseful Improvements in Disinfecting Devices, of which the following is aspecification.

My invention relates to a disinfecting or deodorizing device; and theobject of the in- .vention is to provide a disinfector or deodorizer inthe form of a cake or ball which may be placed or hung where needed andwhich will emit or give off a disinfecting or deodorizing gas or vaporfor several months.

The invention consists generally in a ball or cake of disinfectingmaterial, such as naphthalene, having within it a wicking or core and acontaining vessel for a liquid,whereby said core of wicking is keptsaturated with another disinfecting or deodorizing chemical that isevaporated through the outer shell of the ball.

The invention further consists in the combination,with the innercontaining vessel, of

a wick so arranged therein as to feed the liq-.

uid from the vessel regardless of the position of the same, all ashereinafter described, and particularly pointed out in the claims.

The invention consists particularlyin adisinfecting device comprising aninner ball or bulb filled with a suitable liquid, means for slowlyfeeding the liquid from said ball or bulb, and an outer shell ofvolatile substance molded about or inclosing said inner ball and throughwhich and with which the liquid from said ball evaporates.

The invention will be more readily understood by reference to theaccompanying drawings, forming part of this specification, and in which-Figure 1 is aview of a disinfecting-ball embodying my invention. Fig. 2is a sectional view thereof; Fig. 3 is a similar sectionalviewshowingthe means for filling the inner chamber or vessel.

The shell 2 of the ball is preferably formed of naphthalene, which ismolded thereon and is crystalline in itsformation and is also porous toa limited extent.- With the naphthalene or like material I compound anoil which, being present on the surface of the ball, prevents therapiddeterioration or evaporation fecting liquid 5, preferably carbolic acid.

The vessel t may be closed, as shown in Fig. 2, or it may have a tube 6leading to the surface of the ball and closed by a plug 7. In the lattercase the vessel need not be filled until the ball is completed, whilethe shell of the ball shown in Fig. 2 is only made after the vessel 4has been filled. The vessel 4 is provided with two holes Sin oppositesides, and in these holes I thread a wick 9, the ends of which arepreferably extended into and embedded in the layer of cotton or othermaterial forming the outer wick 3. There is a sufficient slack 10 in thewick within the vessel 4 to allow the wick to always fall into the lowerpart of the ball regardless of its position, and being within the liquidthe liquid will be fed to the outer wicking by capillary attraction. Inthis manner the Wicking 3 is kept saturated with the desired liquid. Theliquid will vaporize and pass through the comparatively porous shell ofnaphthalene, the vapor of which latter volatile substance will be addedto that of the liquid from the vessel 4. The volatilization of thenaphthalene is comparatively slow, and the liquid within the innervessel or chamber is fed so slowly that the ball will act or last for agreat length of time, particularly as the evaporation of the liquid isheld back by the shell of naphthalene. The solid ballthat shown in Fig.2is preferably provided with a loop 11, by which the ball may besuspended.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A disinfecting device, comprising the in ner ball,filled with a suitable liquid, a wick extending from the same, and theouter shell of volatile substance, molded about or inclos ing said innerball and through which and with which the liquid from said ballevaporates, substantially as described.

- 2. Adisinfecting device, comprising an inner ball, filled with asuitable liquid and having a wick extending therefrom, in combina tion,with an inclosing wick cover upon said ICC ball, and a shell of volatilematerial, molded about or inclosin g said ball with its wick covering,all substantially as described and for the purpose specified.

3. A disinfecting device, comprising an inner ball, filled with asuitable liquid and having a Wick extending therefrom, in combination,with an inclosing wick cover upon said ball, and a shell of volatilematerial, molded about or inclosing said ball with its wick covering,said shell having an oily surface to prevent the direct attack ofmoisture thereon substantially as described.

4. A disinfecting device, comprising the inner vessel of non-porousmaterial, filled with
